That might have unintentded consequences, such as leaving a pid in the
cgroup that can't be moved (since it's PF_EXITING) but won't go away
until its threads have all exited.
Maybe that's OK if the other threads are guaranteed to have started
exiting by this point. We'd need some cleanup for when the group
leader finally did exit.
